Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.

|---|---|---|
| Carton (145 units) | Tier 1 | 14-21 days |
| Pallet (1555 units) | Tier 2 | 30-45 days |
| Container (7892 units) | Tier 3 | 21-30 days |

Yes, rolling agreements with defined review points work better for both sides than rigid annual commitments.
